MACHINE FOR CUTTING THE METAL OF SHOW=CASE IVIOLDINGS.

SPECIFICATION forming part of Letters Patent No. 387,408, dated August'7, 1888.

Application filed January 17, i888. Serial No. 261,0l7. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANCIS X. GANTER, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Machines for Cutting the Metal of Show-Gase Moldings, of which the following is a specification.

My invention relates to a machine for cutting metal show-case moldings,and is illustrated in the accompanying drawings, in which- Figure 1 is avertical section of the machine. Fig. 2 is a top view of the machine.Fig. 3 is a front elevation of the machine, in which certain parts areshown in section. Fig. at shows two views of the cutter-shaft drawn toalarger scale. Fig. 5 is a cross section of the feedchute on line 5 5.Fig. 6 shows two views of the cutter-plate on a larger scale. Fig. 7 isa top view of the cutter-plate and the cross-bar on which it is seated.Fig. 8 shows two views of show-case molding, in which two pieces ofmolding, a b, are jointed together by the end of one piece, I), abuttingagainst the side of the other. The abutting end of piece I) is made tofit accurately against the side of piece a by being out with themachine.

The show-case molding-such as may be seen on the show-cases in drug andjewelry storesis composed of wood covered by sheet metal, usually Germansilver. Heretofore in joining two pieces of thismetal-covered molding,asshown in Fig. 8 of the drawings, the fit of the jointed parts has beensecured .by the laborious operation of filing by a hand-file. Themachine shown in the drawings is intended to do this work with accuracyand dispatch, and avoid the necessity of hand-filing referred to.

The letter A designates two standards; B, a crossbar between them andsecured to each standard by screws 0. This crossbar has in one side arecess, d, at the bottom of which is a seat, d, for the cutter-plate e,the cuttingedge e of which is on top. To provide for the verticaladjustment of the cutter-plate 6, two set-screws, f, pass up through theseat d and bear on the bottom edge of the cutterplate, and two otherset-screws, f, enter laterally into holes gin the plate,and each screwprojects through a vertical slot, 9, which opens horizontally throughthe front of the recess in the cross-bar B. It will thus be seen thesaid set-screws f andf enable the cutterplate to be adjusted verticallyto a nicety and hold it firmly.

The cutter h,which coacts with the cuttingedge e on the plate, is on arock-shaft, h, which has bearings in a box on top of the two standards.The top of each standard forms the lower half, 6, of the said box, and ahalf-tubular-shaped plate, I, forms theupper half. This top plate, I,extends entirely across the machine and covers the entire length ofthecuttor-shaft h, except one end, to which a lever or arm, k, isattached, and by which the said cutter-shaft is rocked. This box has aBabbitt-metal lining, Z, and the top plate is secured by the screws m.The top plate has holes a, which provide for oiling the shaft andhearing.

The cutter h is on the center of-the shaft h, and in the present.instance is formed by removing a portion of the rounded side of theshaft, leaving a flat surface, 71., whose edge h serves as the cutter.Thus the cutter h does not project beyond the plane of the rounded sideof the shaft. By grasping the lever k the cutter-shaft h may be rockedbackward and forward in the box I, and thereby the twojaws of thecutter-to wit, the cutter h on the shaft and the edge e on the plate-aremade to coact. It is immaterial to the operation whether the cutter h isformed integral on the rockshaft or not. As the top plate, I, of the boxcovers the cutter-shaft h over its central part, where the cutter h is,it prevents the cuttershaft from springing or yielding when the cuttersh e are acting on the metal molding and enables a small cutter-shaft, h,to be used.

The top plate, I, of the box has at its center and front side afeed-inlet, 0, to admit the end of the metal. molding to the'cutters.

The cutters h 0 may vary in their shape or configuration to be adaptedto various designs of molding, and may have any shape that will bestsuit the particular design that is to be cut. The saidcutters,.therefore, are removable from the machine, and may be exchangedfor others at any time.

A feed-chute, 1?, supports the molding and presents it to the cuttersproperly. This chute has its end connected to the front of the cross ICObar by pivot-bolts which pass through the said end of the chute andthroughlugs q on the cross-bar. A bracerod, r, supports the chute. Thisbracerod has its upper end jointed at s to the chute and projectsdownward to and passes loosely through a roller, 1, supported inbearings I. on the lower edge of the crossbar B. A set'serew, u, in thesaid roller impinges against the brace'rod r and holds it at any desiredpoint. It will be seen the pivoted chute P maybe inclined to any desiredextent. This is of importance, because the same cutters h 0 will have avarying effect on the metal molding by changing the angle of inclinationat which the said molding is presented to the cutters. The same cuttersmay, by thus changing the inclination of the chute P, out one design,I), of molding so that it will joint neatly and accurately with severalother moldings, a, each latter being of different design. The feed'ehutehas a stop-block, 0, Fig. 2, provided with a set-screw, w. Thisstopbloek serves to determine the exact length of the molding as itshall be cut by the machine.

This matching together of two pieces of molding I have here termedjointing. it may properly be termed miter-jointing or mitering, and themoldingpieces which form the joint may meet at any angle.

Having described my invention, I claim and desire to secure by LettersPatent of the United Statesl. A machine for cutting metal show-casemoldings, comprising a cutter-plate, 0. having an edge shaped to fit adesign of molding, and a shaft, h, mounted in suitable bearings, and

intermediate of its ends having a portion of its rounded side1.'emovcd,whereat is asurface, h, whose edge bisects the said roundedside and serves as a cutter, h, to coach with the said cutterplatc.

2. A machine for cutting metal showcase moldings, comprising acutter-plate, c,having an edge shaped to tit a design of molding, ashaft, 7/, provided intermediate of its ends with a cutter, h, which isthe counterpart of the cutter-plate edge and which does not projectbeyond the plane of the rounded side of the shaft, and a boxhearing forsaid shaft,said box-bearing covering the shaft along its length wherethe cutter is.

3. A machine for cutting metal show-case moldings, having in combinationa cross-bar, 13, provided with a recess, d, a cutter-plate, e, occupyingthe recess, a shaft, h, provided in termcdiate of its ends with acutter, h, which is the counterpart of the edge on said cutten plate,and a box-bearing covering the entire length of the cutter-shaft.

i. A machine for cutting metal show-case moldings, having in combinationa stationary cuttenplal'e, e, a shaft, h, provided intermediate of itsends with a cutter, h, which is the counterpart of the edge on saidcutterqdate, and a chute pivoted by one end adjacent to thecutter-plate.

In testimony whereof I affix my signature in the presence of twowitnesses.

FRANCIS X. GANTER.
